The Pericopsis "Consultation" and "Contribution" pages require Javascript to be activated on your browser.
Polygons should be visible except with the "Opera" browser that is currently not compatible with the implemented Google map API. Polygon borders are visible on Internet Explorer (IE6 and upwards), Google Chrome, Firefox and Safari.
This service has not been implemented. However, users are welcome to include a link to their pictures.
The user's e-mail will only be used in the frame of Pericopsis functions or similar tree mapping databases that might be associated in the future. The username is not protected and can be used by everyone knowing it to load the associated polygon. As for any database it’s impossible to guarantee 100% security and we strongly advise the users to not choose the same username or password as for their personal banking operations or mailbox.
It is difficult to predict since Pericopsis is based on the principle of a Wiki. Further evaluations by confirmed botanists would be required.
Pericopsis is planned to be kept free by sponsors, donations and/or advertisements. We plan to open the database
This can be a tricky question. Being visible on Goggle map is definitely an advantage. We would suggest a practical and non academic definition. “Any plant you would rather take a chain saw than shears to harvest”!
Yes. It is possible to follow the growth by publishing the diameter at breast height. Potted trees that are likely to be displaced should not be recorded.
The countries given by Pericopsis are those of the Google reverse geocoding service. This might be frustrating for some users but it was the simplest arbitral choice for the Pericopsis developers.
It is difficult to predict if Pericopsis will encourage or help to reduce illegal logging. The user is in the best place to evaluate case by case if it is reasonably safe to record a tree and/or its diameter. The purpose of Pericopsis is educative and we believe that, in most cases, the risk of tree species extinctions or genetic erosion is higher by ignoring distributions of tree species than by illegal logging. In case of doubt it is always possible to delete a tree from the database.
Logged trees can be removed from the database. Most managed forest or urban trees are expected to be logged according to local managements rules. If you suspect illegal logging activities, you may report the case to the concerned authorities.
